Comparison of the clinical and neuroimaging characteristics of patients with and without dementia in an untreated neurocysticercosis population
Variable | Patients with dementia (n = 14) | Patients without dementia (n = 68) | OR (95% CI) | p value |
---|---|---|---|---|
In the case of numerical variables, the data are expressed in terms of medians and extreme values, given the abnormal distribution according to the Kolmogorov–Smirnov test. | ||||
Patients with delirium (n = 8) were excluded from this analysis because it would have introduced a considerable heterogeneity into the group of patients without dementia. | ||||
*The sample size of the non-demented group for these four variables is only 64 (four patients from this group showed clinically significant intracranial hypertension and thus were not considered for lumbar puncture). | ||||
